x86, gart: add resume handling
If GART IOMMU is used on an AMD64 system, the northbridge registers related to it should be restored during resume so that memory is not corrupted. Make gart_resume() handle that as appropriate. Ref. http://lkml.org/lkml/2008/5/25/96 and the following thread. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Ingo Molnar <mingo@elte.hu>
